Introduction

Sone Shigeru is a notable inventor based in Toyota, Japan. He has made significant contributions to the field of automotive engineering, particularly in the area of engine performance.

Latest Patents

Sone Shigeru holds a patent for a valve timing control apparatus for engines. This innovative device features a cam shaft equipped with a timing change mechanism (VVT) that is driven by hydraulic pressure. The VVT alters the timing of the intake valve, allowing for improved control over the valve overlap between the intake and exhaust valves. This adjustment enhances the suction and exhaust processes within the combustion chamber. The electronic control unit (ECU) plays a crucial role in this system by computing a target value for the valve timing based on the engine's running conditions. It controls the hydraulic pressure supplied to the VVT and monitors the actual valve timing to ensure it remains within a predetermined range. If an abnormality is detected, the ECU executes a fail-safe routine to maintain engine performance.
